Zentangle aka advanced doodling

My new discovery is Zentangle or Zendoodling as some call it. It was invented by Rick Roberts and Maria Thomas and it's really easy to pick up. You create cool patterns by using repetition and line. It is also really easy to get addicted too! But sort of a healthier addiction because it's art. My problem is once I start I don't want to stop...or go to bed.
